Specification of .Letters Patent.

Patented Dee. 3,1912.

Application filed September 3, 1909, Serial No. 516,089. Renewed March2B, 1912. Serial No. 686,972.

To att whom tz may concern.'

Be it known that l, Annen PETERSEN, a subject of the King of Denmark,residing at 'nthrop, in the county of Suiolk and btate of Massachusetts,have invented new and useful Improvements -in Rotary'Braiding-hlachines,of which the following is a specification.

This invention relates to an improved rolo tary braiding machine, andthe object is to provide a braiding machine which shall be capable ofoperating at a high rate of speed and increasing the output overmachines heretofore used. This result is attained by providing' a set ofspoolcarrie'rs traveling in a regular pathof movement in one direction,by providing a body rotating'in the opposite direction andfcarryinganother set of spools and by providing strand carrying .20 levers whichthrow the strands alternately over and under the spool carriers.

Another important result obtained is that no slack forms in the strandsand, therefore, no take-up devices are required. I

:175 The invention consists in the novel feautres of .construction and'in the combination and arrangement of parts set forth in the followingspecification and particularly pointedv out in the appended claims.

Referring to the drawings: Figure 1 is a plan of; a braiding machineembodying my lnventi'on. l Fig. 2 is a side elevation of the same. Fig.3 is a detail sectional view taken on line 3-3 of Fig. 1. Fig. 4 is anenlarged detail plan section taken on line 4-4 of Fig. 2 and partlybroken away to save space in the drawings. Fig. 5 is a side elevation ofone of the strand carrying levers and the bracket on which it ispivotally supported. F ig. 6 is a detail elevation viewed from thecenter of the machine showing two spools of'the upper, series and onespool of the lowerlseries, the lower Spool being shown on its spoolcarrier and driving gears being also shown.

Like numerals refer to like parts through` out .the several views of thedrawings.

Iln thedrawings, 10 is a main driving shaft journaled in bearings 11 andl2 on a 5,0 frame 13 having legs 14 to support the saine on the floor'.A spider l5 constituting a part of the frame of the ,maehineis providedwith a hub 16 in-which is secured a hollow stationary spind1e'l7surmountedby'a. bushing 18. A sleeve 19 journaled on the spindle 17 hassecured thereto a bevel gear 20 meshing into a bevel pinion 21 fast tothe shaft 10, said gear and sleeve being preferably supported upon aradial ball bearingl 22. Journaled on the sleeve 19 is a miter gear 23meshing into a miter gear 24 fast to the shaft 10, the former gear beingpreferably supported upon a radial ball bearingl 25. Fast to the .mitergear 23 is a large evel gear 26 in to which a series of bevel pinions 27mesh, said bevelpinions being mountedy on shafts 28. The plnions 27 arearranged in pairs and the shafts of each pair terminate in a bracket 28fast to a rotary member 29, while the outer ends of said shaftsterminate in a ring 3() which is secured to the member 29 by a series ofwebs or spokes 31 thus constituting the member.. 29 'and the ring 30 asingle rotating body, the member 29 being fast to and driven by thesleeve 19.l

It will be understood'by observing the ratio of the gears 20 and `21 andgears '23 and 24, that the member 29axid ring 30 are rotated in thesaine direction as the gear 26', but at a less speed, the consequencebeing that the bevel pinions 27 are rotated on their own axes andrevolved about the gear 26.

A series of thread-mass carriers 32 all .separatev and distinct fromeach other are mounted to slide in ways 33 formed in the ring 3() andupon ways 34 formed onthe brackets 28', said thread-mass carriers havingformed thereon or fast thereto segmental gears 35i which are adapted4 tomesh into the pinons 27 in succession cach segmental gear being arrangedto mesh with each succeeding pinion before passing out of mesh with thepreceding pinion. be seen that the thread-mass carriers 32l are revolvedabout the ecnlerof the machine in a direction opposite 'to the directionof rotation of. the ring 30 andmember 25) and are maintained in theirproper spacing with relationto each other.

Each of the thread-'mass Carriers 32 supports a spindlc upon which thcspool 37 is mounted to rotate.

- upon a rod 40 fast to said spool cartier the several strands' leadingfrom ther-'several lthread carriers 39 tothe braiding point at Thethread wound on` the spool 37 `leads therefrom around a guard.

ln this way it will ring-30, the threads leading from Vtheir respectivespools to thread guides 45, respectively, and thence through threadguides 46,

v respectively, secured to brackets 47 mounted upon the ring 30, thelast mentioned thread guides being located at'the axes of strandcarrying levers 48 pivotally supported upon said brackets. The threadspass'from the thread guides 46 through thread guides` V49,

' 50 and 5l mountedl upon the levers 48 and thestrands extend from thelast-mentioned thread guides through vertical slotsi52 in the ring 30and through the spaces-'Which separate lthe brackets 28 from each other,to the braiding point atthe bushing 18. The funcpose said levers havejournaledthereon Cain tion of the strand carrying levers 48 is to throwtheir strands alternately over and under the thread-mass carriers 32 tocause 'tivo series of strands to interlace With each other at thebraiding point and for this purrolls 53 located in a serpentine slot 54in a stationary cam 55 mounted on uprights 56 forming a part of theframe13.

It will be observed that the t-Wo series of spools move .in regularcircular paths -con-` centric with thecenter of the machine andthe-"only reciprocating pa'rts of the machine are the strand carryinglevers 48, and it is possible to make these levers so light that themachine is capablev of operating at a much higher speed thanhas-heretofore been possible. Furthermore, it is possible by increasingthe number of the Strand carriers as by having two strand carrierstoeach spool carrier to interlace the strands to introduce a greaternumber of strands than there` are spool carriers, if desired, thuscausing the fabric to be built up With greater rapidity than hasheretofore been possible.`

1 I will now proceed to describe the' feeding mechanism. The hub 16 ofthe spider 15 supports a i* bracket 57 on which is rotatably supportedan idler drum58 which guides the braided fabric as it passes'downwardlyinside of the hollow spindle I7. vThe fabric passes from the idler 58lseveral times around a feed` drum 59- -fast to a shaft 60 journaled ina vbearing 61.f ast to the frame 13, said shaft having fasttlierto abevel gear 62 meshing into a bevel pinion 63. 1 The bevel pinion 63 Y is'fastito a shaft 64 journaled in bearings 65 and 66, said shafthavingalso fast thereto ,a'wo-rm'gear 67 which meshes with a worm 68fastfto the main driving shaft 10.- -As the mainfidriving shaft Visrotated, the gearing just described imparts the proper rotation to thefeed drum 59, therebyfeeding. the fabric from the machine at the'properspeed.

Yhile I have described the ring 30 carrying one setof spools` asrotating in one directionand the spool carriers 32 carrying the otherset of spools as revolving inthe opposite direction, it uill be evidentthat vtheir motion is necessarily only relative and I have chosen in thepresent instance to move them in opposite directions forcenvenienceof-construction and for attaining two to increase the speed of operationof the machine Without increasing the actual speed of rotation of anyone of itsparts.

Having thus described'my invention, what -cure is:

1.v A rotary braiding machine having, in combination, a series ofthread-mass carriers having segmental gears thereon, a series of pinionsadapted to mesh successively with said segmental gears, a gea-i' meshingwith said pinions, a body on which said pinions are journaled and uponwhich said carriers are supported and guided,a series 'of threadmasssupports mounted on said body, means to imparta rotary motion tosaidbody and said gear in the same direction but at differentspeeds, aseries of strand-carriers carried by said body, and means acting on saidstrand-carriers to cause'the same to carry the strands leading from saidthread-mass supports alternately over and under said thread-masscarriers.
